This is a cruel joke if my body is playing tricks on me

.
I spotted yesterday afternoon- a dark yellowish or light brown and was having EWCM.. and assumed AF is coming (today is CD29- usually cycles run 30-31 days but this is my first one since m/c). Today, a little more cramping and now pink spotting, which I have never had before, ever. Usually I always spot before AF but it is dark like old blood and then AF comes on full force. I counted back and we DTD 8 days ago and 12 days ago, which would make it possible that this is implantation bleeding if I ovulated sometime in between there.
I hate that I keep thinking there is a chance.

I have no bloating which usually comes before AF and I am not having the horrible cramps I’m used to. What gives?
